UNITED NATIONS (AP) — The U.N. health chief says positive results from coronavirus vaccine trials mean the world “can begin to dream about the end of the pandemic.” But the director-general of the World Health Organization says rich and powerful nations must not trample the poor and marginalized “in the stampede for vaccines.” Tedros Adhanom Ghebreyesus told the General Assembly’s first high-level session on the pandemic that while the virus can be stopped, “the path ahead remains treacherous.” Tedros said Friday that the pandemic has shown humanity at “its best and worst,” pointing to acts of compassion and scientific achievements but also “signs of self-interest, blame-shifting, and divisions.” 713

Tumblr, a popular blog service owned and operated by Yahoo, says it will ban "adult content" from its site on Dec. 17.The decision comes just weeks after the Tumblr app was temporarily removed from Apple's App Store after child pornography was found on the site. Tumblr said in a statement to The Verge that the decision to ban adult content did not stem from that incident.Tumblr's new policy bans "explicit sexual content" and most instances of nudity. The site added that nudity "found in art," as well as nudity in the context of health-related situations and in the context of political protest or newsworthy events would still be permitted.Tumblr also says that written erotica will still be permitted on the site.After Dec. 17, any explicit content flagged by algorithms will be hidden from public view but not deleted from the site. Users can appeal Tumblr's decision if they feel it was made in error. 953

Two liters of Dr. Pepper costs .80 at a Dollar General store in Union City, NJ. A 10-oz bag of Twizzlers sells for .50. But the low-end retailer is attempting a high-end revamp of its food offerings — adding yogurt, nuts, protein bars, veggie snacks, and coconut water to meet customer demand for healthier choices.Dollar General (DG) has recently added around 125 "better for you" items to its shelves in 2,700 stores. The products appear under Dollar General's Good & Smart house brand, and the store also carries Annie's, Back to Nature, Honest, Nature Valley, and Kashi brands. On Tuesday, Dollar General said the initiative was performing better than it expected, and it has plans to roll out to more stores next year.The chain began offering the products after getting feedback from shoppers who could not find affordable food with low sodium, calorie, fat and sugar levels or without artificial sweeteners, said Dollar General's Chief Merchandising Officer Jason Reiser."These types of healthy food options seemed out of reach," Reiser said.Dollar General's move signals the wider consumer shift to healthier foods is beginning to take hold among low-income shoppers. Dollar General, which sells most of its items for under , serves a wide range of demographics. But its primary customers are value-conscious?and come from low-and-fixed income households."Our core customer is always a little bit behind the curve," Dollar General CEO Todd Vasos said at a conference earlier this year. "Better-for-you is starting to emerge as a trend." 1573

Twenty-three and a college graduate, Angela Pennella's life was just beginning. But a split-second moment marked the beginning of a life forever changed."It was a day I didn't see coming," said Pennella. "There was a lot of emotion. I was angry, really sad. I lost most of my 20s from that day that was almost fatal."She was five minutes away from home when a reckless driver crossed the double yellow lines going 55 MPH in a 35-MPH zone, hitting her head-on."I don't remember much of that day at all, but that's the day that really changed my life," said Pennella.She was cut out of the vehicle and flown to the hospital with a lacerated liver, punctured lung, and four broken ribs, ultimately receiving over 1,000 stitches to her face and body. But it's the injury you can't see that lives with her 18 years later."The brain is this powerful tool, so beautiful. But it can also really get you down and bring you to a place that isn't who you are," said Pennella,She suffered a severe brain injury and had to re-learn how to talk again. Today, she still struggles with memory problems and mental exhaustion after everyday tasks."Once the brain is injured, it is hard to reverse that injury," said Ian Grover, medical director for the Hyperbaric and Wound Care Center at UC San Diego Medical Center.Researchers at UC San Diego Health have joined a national research study called Hyperbaric Oxygen Brain Injury Treatment (HOBIT) to assess whether the approach might also benefit patients with severe brain injuries."Because there's such time urgency, we need to get patients identified, stabilized, and get them into that hyperbaric chamber within eight hours," said Todd Costantini, the trauma medical director at UC San Diego Health. Traditionally used to treat wounds and decompression sickness in divers, patients in a hyperbaric oxygen chamber receive 100 percent oxygen in a pressurized room."The theory is that the hyperbaric oxygen will one, decrease swelling of the brain after it's been injured. And number two, it will deliver oxygen to the injured tissue," Costantini said.It's the first time this therapy is being used to treat patients in the hours after injury. Because they may still be unconscious, the study required special permission from the FDA. Participating hospitals are doing outreach to inform and educate their communities on the research."In medicine, we’ve made a lot of progress treating cancer, sepsis, those kinds of things. But in the last 20-30 years, we haven’t made significant improvement in the treatment of traumatic brain injuries,” said Grover.Because of cost and the staff required to operate this equipment; chambers are disappearing from centers nationwide. But with a brain injury occurring every 15 seconds in the United States, doctors at the participating hospitals hope the study’s results will be enough to bring the chambers back."Just to see how it would've reduced the inflammation, maybe I wouldn't have been in the ICU as long, or gained consciousness back faster," said Pennella, after learning about the research.Pennella is now an advocate, helping other brain injury survivors cope through the San Diego Brain Injury Foundation, where she is also on the board of directors. "After I went through my injury and recovery, I knew I wanted to do inspirational speaking and writing anyway that I could to just share my story to bring hope," said Pennella.Meditation, prayer, exercise, and gratitude journaling have been instrumental in her recovery. Pennella consistently practices cognitive fitness to help keep her memory fresh."If you think you can, you're halfway there," said Pennella. 3653

Twitter said late Thursday it was changing its policy on hacked content after an outcry about its handling of an unverified political story that sparked cries of censorship from the right. An executive tweeted that the social media company will no longer remove hacked material unless it’s directly shared by hackers or those working with them. Instead of blocking links from being shared, tweets will be labeled to provide context.Twitter and Facebook had moved quickly this week to limit the spread of the story published by the conservative-leaning New York Post, which cited unverified emails regarding Democratic presidential nominee Joe Biden’s relationship with Ukraine between him and his son, Hunter.The origins of the story also trace back to Trump lawyer Rudy Giuliani, who has repeatedly pushed unfounded claims about Biden and his son. Even if the emails in the Post are legitimate, they don’t validate Trump and Giuliani’s claims that Biden’s actions were influenced by his son’s business dealings in Ukraine.The email reportedly is from Vadym Pozharskyi, an adviser to the board of Ukranian energy company Burisma. Pozharskyi wrote to thank Biden "for inviting me to DC and giving an opportunity to meet your father and spent (sic) some time together. It’s realty (sic) an honor and pleasure.”Giuliani claims the emails were taken from a laptop that was dropped off at a Delaware computer repair shop in 2019, which was never picked up by the owner. The Post reported that the shop owner could not positively identify whose laptop the emails were taken from, but said the computer had a sticker for the Beau Biden Foundation.The Biden campaign told the Associated Press that it could not find a meeting between the then vice president and Pozharskyi on Biden's schedule. 1793
